Is the noise produced by air conditioning units a source of annoyance, or is a slight increase in volume a fair trade-off for the refreshing coolness they provide?
In the quest for comfortable cooling, the noise produced by air conditioning systems is a significant factor to consider. Here's a breakdown of the sound levels of various air conditioning units to help you make an informed decision.
All heat pumps and air conditioning systems must bear a CE label, stating their sound levels for transparency. This label ensures that consumers are well-informed about the noise their chosen appliance will produce.
Fixed air conditioning systems, such as mounted split or window units, are generally quieter, producing noise levels between 20 and 40 decibels. This is quieter than a normal conversation and less intrusive in living spaces. For instance, the indoor units of modern fixed air conditioning systems are designed to be whisper-quiet, producing around 50 - 55 decibels of sound, comparable to low background music or a modern fridge running.
On the other hand, portable air conditioners are noisier due to their all-in-one design and portable function. They typically produce noise levels between 50-65 decibels, depending on the model and setting. However, the quietest portable models can operate as low as 40–50 dB, suitable for bedrooms or study environments.
The outdoor units of fixed air conditioning systems are louder than the indoor units, producing around 60 to 65 decibels of sound. In contrast, a portable air conditioner's noise level is comparable to a dishwasher, light traffic, or a normal conversation.
To reduce the noise produced by portable air conditioners, one can check the decibel ratings on the product description or look for units that are Quiet Mark rated. For example, some Bosch indoor units have a 'silent mode' feature which reduces the indoor sound to 21 decibels.
It's worth noting that heat pumps are not permitted to produce more than 65-70 decibels, depending on their power. The Duux Whisper fan, currently available on next day Prime delivery, runs quietly at just 13 dB and has 26 different speeds.
Air treatment experts and industry professionals agree on the importance of this noise difference for use-case considerations. Quieter fixed units are preferred for long-term home cooling, especially in bedrooms or quiet areas, while portable units may be noisier but offer mobility and ease of installation.
Katie Lilywhite, an air treatment expert at AO.com, and Hamid Salimi, a mechanical engineer with over 13 years of experience at Daikin, both emphasize the significance of considering noise levels when choosing an air conditioning system. Adam Knight, a lead engineer at heating and cooling experts, BOXT, with over 17 years of industry experience, also highlights the importance of understanding the decibel ratings to ensure a peaceful living environment.
In conclusion, while both fixed and portable air conditioning systems serve the purpose of cooling, their noise levels vary significantly. By considering the decibel ratings and understanding the noise levels associated with each type of air conditioning system, consumers can make informed decisions to maintain a peaceful living environment.
- Fixed air conditioning systems, such as mounted split or window units, produce noise levels between 20 and 40 decibels, ensuring a quiet living space.
- Modern fixed air conditioning systems are designed to be whisper-quiet, with indoor units producing around 50 - 55 decibels, comparable to low background music or a modern fridge running.
- Portable air conditioners are noisier, typically producing noise levels between 50-65 decibels, but the quietest models operate as low as 40–50 dB, making them suitable for bedrooms or study environments.
- The outdoor units of fixed air conditioning systems are louder, producing around 60 to 65 decibels of sound, comparable to a dishwasher or light traffic.
- To reduce the noise produced by portable air conditioners, consumers can check the decibel ratings on the product description or look for units that are Quiet Mark rated, like some Bosch indoor units with a 'silent mode' feature.
- Heat pumps are not permitted to produce more than 65-70 decibels, and the Duux Whisper fan, currently available on next day Prime delivery, runs quietly at just 13 dB and has 26 different speeds.
- Katie Lilywhite, an air treatment expert, Hamid Salimi, a mechanical engineer, and Adam Knight, a lead engineer, all stress the importance of considering noise levels when choosing an air conditioning system, and understanding the decibel ratings to ensure a peaceful living environment.
